launch message: reasoning before the plan (owner ruling, 2026-09-26)

The probe→teach handoff wake read as a dispatch order ("Author the session's
plan map now") and the teacher skipped the deliberation the planning fragment
asks for. The wake now paces it: take your time, read the assessment and the
probing transcript, reason out the optimal way to teach this person this
thing — floors, ceilings, misconceptions, the minimal tree so every step
lands as obviously true — and only then call plan_init. Machinery honest:
plan_init is still the first tool, the plan map still the first artifact, and
the tail now says to wait for his verdict (which is what presenting actually
does — the old "then begin teaching" tail skipped the verdict seam).
